Musk Writes $276 Million in Checks, Three Days Before the Filings Come Due

Elon Musk has handed Republican super PACs and party committees more than $276 million since July, according to figures his own representatives provided to The New York Times and confirmed Monday by his political operation. That makes him the largest known donor of the 2026 midterm cycle, with three weeks left before voters go to the polls on Nov. 3.

Add the earlier checks and Musk's federal political spending for the 2025-26 cycle comes to roughly $366 million, as CNBC reported. That is more than he spent in 2024, when his giving ran somewhere between $250 million and nearly $300 million depending on which tally you use, and it comes after Musk said in 2025 that he intended to spend "a lot less" on politics.

One caveat belongs up top: none of this has been confirmed by a public document yet. The numbers came from Musk's side, not from the Federal Election Commission. The quarterly disclosure deadline falls Thursday, Oct. 15, which is when the receipts either match the announcement or they don't.

Where the Money Went

The single largest piece, $158 million, went to the Senate Leadership Fund, the main super PAC working to hold the Republican Senate majority. CNBC noted that a donation of that size ranks among the largest known individual political contributions in American history. The group announced a roughly $350 million, eight-state Senate program back in April; by simple arithmetic, Musk's check covers about 45 percent of it.

From there the list spreads out. More than $76 million went to America PAC, the vehicle Musk founded in 2024, whose spokesperson Lindsey Curnutte confirmed the overall figure to CNBC on Monday. Twenty million went to the Congressional Leadership Fund, the House Republican super PAC. Newsweek, reviewing the breakdown, reported $10 million to Lone Star Liberty PAC, which is backing Texas Senate candidate Ken Paxton, $10 million to the Republican Governors Association and $2 million to the Republican Attorneys General Association. A separate aggregate figure, drawn from a secondary tally rather than any one of those outlets, puts roughly $42 million more across four additional Republican groups.

The Texas line is worth noting. CNN pointed out that the Senate Leadership Fund is spending heavily to defend a Texas seat in a state that happens to be central to Musk's companies. Earlier in the cycle, Newsweek found, he put $5 million into a PAC supporting Vivek Ramaswamy's run for governor of Ohio and $10 million into a Kentucky group backing Nate Morris, who later withdrew from the Senate primary against Rep. Andy Barr. An FEC review by Newsweek also turned up direct contributions to more than 21 House and Senate Republicans, including Lauren Boebert, Anna Paulina Luna and Abe Hamadeh.

The Feud Is Over, Apparently

The political arc here is hard to miss. Musk endorsed Donald Trump in July 2024, poured money into that race, ran the Department of Government Efficiency starting in January 2025, then had a loud and public falling-out with the president by mid-year. He pledged to pull back from political giving. In June 2025 he gave $5 million to MAGA Inc. anyway. By December, Axios was reporting he planned to re-enter the midterms. In early October, Trump awarded him the National Medal of Science.

Not everyone thinks the money buys much this late. Todd Belt, who teaches political management at George Washington University, told Newsweek the timing works against it.

"I don't see how a bunch of spending right at the end is going to change many people's minds."

Sen. Bernie Sanders took the opposite view. In a post on X reported by Newsweek, the Vermont independent wrote that Musk is "spending $366 million to keep Republicans in control of Congress" and added, in his own words, "STOP MUSK. STOP OLIGARCHY." Musk himself has said nothing publicly about the figures. Newsweek said it sought comment through SpaceX and Tesla; The Hill reported it contacted the Congressional Leadership Fund, the governors and attorneys general associations, Lone Star Liberty PAC and the Senate Leadership Fund without a response.

What "Largest Known" Actually Means

The phrase doing the work in every headline is largest known. Super PACs disclose their donors; 501(c)(4) groups do not. Whatever flows through nonprofit channels on either side stays invisible, which is why a title like "biggest donor of the midterms" is always provisional. America PAC alone has reported more than $52 million in federal disbursements since January 2025 in its FEC filings.

Thursday's deadline is the test. The filings from the Senate Leadership Fund, America PAC and the Congressional Leadership Fund should show the amounts, the transfer dates and any recipients that haven't been named. Until then, the biggest political donation story of the cycle rests on a number supplied by the donor.
